Genesis 46:16-18

And the sons of Gad: Ziphion, and Haggi, Shuni, and Ezbon, Eri, and Arodi, and Areli. And the sons of Asher: Imnah, and Ishvah, and Ishvi, and Beriah, and Serah their sister; and the sons of Beriah: Heber, and Malchiel. These are the sons of Zilpah, whom Laban gave to Leah his daughter; and these she bare unto Jacob, even sixteen souls.
